A cooling water pipe with uniform heat exchange

Abstract

This utility model discloses a cooling water pipe with uniform heat exchange, relating to the field of cooling water pipes. The utility model includes a cooling water pipe with flanges installed at both its inlet and outlet ends, and two sleeves fitted onto the outer wall of the cooling water pipe. This utility model incorporates sleeves, a photoelectric liquid level sensor, wires, locking bolts, and self-locking nuts. After the worker connects the cooling water pipe to an external pipeline via the flanges, the two sleeves are installed at both ends of the cooling water pipe. If the seal at the flange connection fails, liquid leakage will occur, flowing into the sleeves and accumulating there. At this time, the photoelectric liquid level sensor detects the liquid level in the sleeves and transmits the signal to an external PLC controller via the wires. The external PLC controller then activates an external audible and visual alarm to alert the worker to the liquid leak at the connection between the cooling water pipe and the external pipeline, facilitating timely repair of the connection.

Description

Technical Field

[0001] This utility model relates to the field of cooling water pipes, specifically a cooling water pipe with uniform heat exchange. Background Technology

[0002] Cooling water pipes with uniform heat exchange are widely used heat exchange components in many fields such as industrial production and refrigeration and air conditioning. Their working principle is mainly based on the principles of heat conduction and heat convection. When the cooling medium (such as water, coolant, etc.) flows in the cooling water pipe, the heat of the object being cooled is transferred to the cooling water pipe wall through heat conduction, and then transferred to the cooling medium by the pipe wall. At the same time, the cooling medium continuously carries away the heat through heat convection during the flow in the pipe.

[0003] Existing cooling water pipes with uniform heat exchange require connection to external pipelines after installation to allow water to flow within the pipes. Since these connections are made by welding or flanges, welding makes maintenance difficult, and while flanges provide sealing rings to improve the seal, these rings age over time, leading to seal failure. When a leak occurs at the flange connection, water leaks from the gap between the pipe and the flange. If this leak is not detected and addressed promptly, it can result in cooling medium loss, system pressure drop, and reduced cooling efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cooling water pipe with uniform heat exchange, so as to solve the technical problem that it is difficult for staff to detect and repair water leakage in a timely manner when the flange sealing ring fails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling water pipe with uniform heat exchange, comprising a cooling water pipe, wherein flanges are installed at both the inlet and outlet ends of the cooling water pipe, two sleeves are fitted on the outer wall of the cooling water pipe, and a first side plate and a second side plate are respectively installed at the top and bottom of the two sleeves, and a first sealing ring is installed on one side of each of the two sleeves, a locking bolt is installed between the first side plate and the second side plate, and a photoelectric liquid level sensor is installed at the bottom of the sleeve, and a wire is connected to the bottom end of the photoelectric liquid level sensor.

[0006] By adopting the above technical solution, if liquid leakage occurs at the flange connection, the liquid will flow into the sleeve, and at this time the photoelectric liquid level sensor will detect the amount of liquid in the sleeve.

[0007] Furthermore, one end of the locking bolt is threaded with a self-locking nut, which fits against the second side plate.

[0008] By adopting the above technical solution, the stability of the locking bolt can be improved when the self-locking nut is screwed onto the locking bolt, and the stability of the two sleeves after they are closed can also be improved.

[0009] Furthermore, the two first sealing rings are fitted together, and the first sealing rings are made of fluororubber material.

[0010] By adopting the above technical solution, the sealing performance after the two sleeves are closed can be improved, preventing liquid leakage.

[0011] Furthermore, the cooling water pipe is equipped with multiple supports inside, and a spiral baffle is installed between every two supports.

[0012] By adopting the above technical solution, the spiral turbulence plate forces the water flow to spiral forward along the pipe wall, breaking the "laminar flow" state, increasing the disturbance between the water flow and the pipe wall, thinning the thermal boundary layer, and improving the local heat exchange efficiency.

[0013] Furthermore, both sleeves are semi-circular rings, and the sleeves are made of 316L stainless steel.

[0014] By adopting the above technical solution, the sleeve made of 316L stainless steel can be prevented from rusting, thereby extending the service life of the sleeve.

[0015] Furthermore, the flange is located inside the sleeve.

[0016] By adopting the above technical solution, when water leakage occurs at the flange connection, water will flow into the inside of the sleeve.

[0017] Furthermore, two positioning plates are installed inside the sleeve, and the positioning plates are fitted to the flange.

[0018] By adopting the above technical solution, the positioning plate can position the sleeve and prevent the sleeve from moving randomly.

[0019] Furthermore, the wire is a shielded cable, and the wire is connected to the data input terminal of an external PLC controller.

[0020] By adopting the above technical solution, the conductor is a shielded cable to prevent electromagnetic interference and electromagnetic radiation.

[0021] Furthermore, the sleeve is detached from the cooling water pipe.

[0022] By adopting the above technical solution, the sleeve can be removed from the cooling water pipe.

[0023] Furthermore, the inner wall of the sleeve is provided with a second sealing ring, which fits against the outer wall of the cooling water pipe.

[0024] By adopting the above technical solution, the second sealing ring can improve the sealing performance between the sleeve and the cooling water pipe, preventing water leakage.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model includes a sleeve, a photoelectric liquid level sensor, wires, locking bolts, and a self-locking nut. After the worker connects the cooling water pipe to the external pipe through a flange, two sleeves are fitted onto the outer walls of the cooling water pipe and the external pipe. When the two sleeves are closed, the locking bolts can be screwed into the first and second side plates, and then the self-locking nut can be screwed onto the locking bolts and fitted into the second side plate. At this time, the installation of the sleeve is completed. If the seal at the flange connection fails, liquid leakage will occur, and liquid will flow into the sleeve and accumulate inside. At this time, the photoelectric liquid level sensor will detect the liquid level in the sleeve and transmit the signal to the external PLC controller through the wires. The external PLC controller will then activate the external audible and visual alarm to remind the worker that liquid leakage has occurred at the connection between the cooling water pipe and the external pipe, so that the worker can repair the connection in time and avoid continuous liquid leakage that affects the flow efficiency of water in the cooling water pipe.

[0027] 2. This utility model has a first sealing ring and a second sealing ring. The first sealing ring improves the sealing performance of the two sleeves after they are closed, preventing liquid leakage. The second sealing ring improves the sealing performance between the sleeve and the cooling water pipe, preventing liquid leakage. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A cooling water pipe with uniform heat exchange, such as Figures 1-5 As shown, the device includes a cooling water pipe 1, with flanges 4 installed at both the inlet and outlet ends of the cooling water pipe 1. Two sleeves 9 are fitted on the outer wall of the cooling water pipe 1, and a first side plate 5 and a second side plate 12 are installed at the top and bottom of the two sleeves 9, respectively. A first sealing ring 8 is installed on one side of each of the two sleeves 9, and the two first sealing rings 8 are fitted together. The first sealing rings 8 are made of fluororubber material to improve the sealing performance after the two sleeves 9 are closed and prevent liquid leakage. The sleeves 9 are detached from the cooling water pipe 1 so that the sleeves 9 can be removed from the cooling water pipe 1.

[0038] Specifically, a locking bolt 6 is installed between the first side plate 5 and the second side plate 12. A photoelectric liquid level sensor 10 is installed inside the lower part of the sleeve 9, and the bottom end of the photoelectric liquid level sensor 10 is connected to a wire 11. If liquid leakage occurs at the flange 4 connection, the liquid will flow into the sleeve 9. At this time, the photoelectric liquid level sensor 10 will detect the liquid level in the sleeve. The wire 11 is a shielded cable and is connected to the data input terminal of the external PLC controller. The wire 11 is a shielded cable to prevent electromagnetic interference and electromagnetic radiation. In addition, the operator also needs to connect the audible and visual alarm (not shown in the figure because the audible and visual alarm is not shown in the figure). The alarm is not installed on the cooling water pipe. It is installed in areas where operators frequently move around, such as the aisles of the workshop or near the equipment operating station. The external sound and light alarm also needs to be connected to the external PLC controller via cable. Both sleeves 9 are semi-circular rings. The sleeves 9 are made of 316L stainless steel. The use of 316L stainless steel can prevent the sleeves 9 from rusting, thereby extending the service life of the sleeves 9. In large cooling water pipe systems or scenarios that require remote monitoring, the signal of the photoelectric liquid level sensor 10 is connected to the monitoring system or host computer via wire 11 (as the operator decides).

[0039] See Figures 1-4The flange 4 is located inside the sleeve 9. When water leaks at the connection of the flange 4, water will flow into the inside of the sleeve 9. Two positioning plates 13 are also installed inside the sleeve 9. The positioning plates 13 fit with the flange 4 and can position the sleeve 9 to prevent it from moving at will. Multiple supports 2 are installed inside the cooling water pipe 1, and a spiral baffle 3 is installed between every two supports 2. The spiral baffle 3 is made of stainless steel. The spiral baffle 3 forces the water flow to spiral forward along the pipe wall, breaking the "laminar flow" state (laminar flow is easily formed when the flow rate is slow, and the heat exchange efficiency is low), increasing the disturbance between the water flow and the pipe wall, making the thermal boundary layer (the thin layer near the pipe wall, where heat transfer is slow) thinner, improving the local heat exchange efficiency, and improving the heat exchange uniformity.

[0040] Example 2:

[0041] Based on the above embodiment 1, the following structure will be set to improve the stability of the locking bolt 6.

[0042] Specifically, one end of the locking bolt 6 is threaded with a self-locking nut 7, which fits against the second side plate 12. When the self-locking nut 7 is screwed onto the locking bolt 6, it can improve the stability of the locking bolt 6 and the stability of the two sleeves 9 after they are closed.

[0043] Example 3:

[0044] Based on the above embodiment 1, in order to improve the sealing between the sleeve 9 and the cooling water pipe 1, the following structure will be set.

[0045] See Figures 1-4 The inner wall of the sleeve 9 is provided with a second sealing ring 14, which fits against the outer wall of the cooling water pipe 1. The second sealing ring 14 is made of fluororubber material. The setting of the second sealing ring 14 can improve the sealing performance between the sleeve 9 and the cooling water pipe 1 and prevent water leakage.

[0046] The working principle of this utility model is as follows: First, the operator installs the cooling water pipe 1 and connects it to the external pipe through the flange 4. After installation, two sleeves 9 are fitted onto the cooling water pipe 1 and the outer wall of the external pipe (i.e., the outer perimeter of the flange 4). When the two sleeves 9 are closed, the locking bolt 6 can be screwed into the first side plate 5 and the second side plate 12. Then, the self-locking nut 7 is screwed onto the locking bolt 6 and fits against the second side plate 12. At this time, the installation of the sleeves 9 is completed. Next, the wire 11 is connected to the data input terminal of the external PLC controller. The operator also needs to install the audible and visual alarm (not shown in the figure because the audible and visual alarm is not installed on the cooling water pipe) in the area where the operator frequently moves, such as the aisle of the workshop, near the equipment operating station, etc. The audible and visual alarm installed externally also needs to be connected to the external PLC controller through the cable. In large cooling water pipe systems or scenarios that require remote monitoring, the signal of the photoelectric liquid level sensor 10 is connected to the monitoring system or host computer through the wire 11 (depending on the situation).

[0047] After installation, water can flow inside the cooling water pipe 1. If the seal at the flange 4 connection fails, liquid leakage will occur, and the liquid will flow into the sleeve 9 and accumulate inside the sleeve. At this time, the photoelectric liquid level sensor 10 will detect the liquid level in the sleeve and transmit the signal to the external PLC controller through the wire 11. The external PLC controller will then activate the external audible and visual alarm to remind that liquid leakage has occurred at the connection between the cooling water pipe and the external pipeline, so that the staff can repair the connection in time and avoid continuous liquid leakage that affects the flow efficiency of water in the cooling water pipe 1.
